After losing both parents in a fatal plane crash, teenager Ryuuichi Kashima must adjust to his new life as the guardian of his younger brother Kotarou. Although Ryuuichi is able to maintain a friendly and kindhearted demeanor, Kotarou is a reserved toddler still too young to understand the reality of the situation. At their parents' funeral, they are approached by Youko Morinomiya, the stern chairman of an elite academy, who decides to take them under her care. However, there is one condition Ryuuichi must fulfill in exchange for a roof over their heads and enrolment in the school—he must become the school's babysitter. In an effort to support the female teachers at the academy, a babysitter's club was established to look after their infant children; unfortunately, the club is severely short-staffed, so now not only is Ryuuichi responsible for his little brother, but also a handful of toddlers who possess dynamic personalities.

A group calling themselves The Individual Eleven has begun committing acts of terror across Japan. While Motoko Kusanagi, Daisuke Aramaki, Batou, and the other members of Section 9 investigate this new menace, the Japanese government faces a separate crisis, as foreign refugees displaced by the Third World War seek asylum in Japan. But as the members of the special-ops team continually encounter Gouda Kazundo—a leading member of the Cabinet Intelligence Service—in their hunt, they begin to suspect that he may be involved, and that the events of the refugee crisis and The Individual Eleven may be more connected than they realize...
